Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

Updating a lighting system to improve energy efficiency seems like a no brainer. The facilities in the space will be improved, and it saves the owner money. What could be the problem with that?

According to a recent report from the American Council for an Energy Efficient Economy (ACEEE), demand-response programs can reduce utilities' peak demand an average of 10 percent, complementing savings from energy efficiency programs.

Imagine storing summer heat. Renewable energy has always been about the art of the possible, turning the obvious and plentiful into a reliable source of clean fuel. If the wind, waves and even the almighty sun can be harnessed for generation, almost anything else can be captured, too.

Safety has always been one of the biggest knocks against nuclear power. A standard adopted in March 2016 by the Institute of Electrical and Electronics Engineers (IEEE) and the International Electrotechnical Commission (IEC) could further the industry’s neverending quest to address those concerns.

Where are the Fiber Optic Jobs?

Since the fiber optic “bubble” burst a couple of years ago, employment ads for fiber optic installers have been scarce. But are real jobs still available? If so, where are they? Is the outside plant market dead? What about premises applications? What technologies are driving new installations?

Testing for Category 6 Cabling

As you may know, the Telecommunications Industry Association (TIA) has agreed that Level III-qualified testers are to be used when certifying or verifying Category 6 cabling systems (Category 6 cable is a 100-Ohm cable with transmission characteristics specified up to 250 MHz).

The Little Engine that Could

Ask most electrical contractors about the latest cogenerating technology—microturbines—and you’re likely to get silence, or possibly: “micro-what?” This technology, which has only been on the market a few years (Capstone Turbine’s C30 model was introduced in December 1998), may still be relatively u
